So did PS2 the DS and Wii, which are some of the most successfull consoles. PS3 had also a mandatory HDD which brought up the price and skewered any comparison with the cheapest available XBox.
For me 100$ are worth it, since I can easily then skip rebuying the games I already possess.
Also I dont know why you dont get it, im fine with a BC-less SKU or an addon via PCIe. So I dont know why you continue to whine about it - I hate repeating myself 2 times.
1. They're not successful because of BC. Sure didn't help PS3 a whole lot.
2. Mandatory HDD didn't bring up the price too much for the PS3. A host of other components brought it sky high.
3. $100 may be worth it for you. Is it worth it for Sony to design around, test, and bring it to market? Probably not.
If someone is really going to throw such a tantrum about having BC, a good working PS3s will very likely be avaliable at ~150 USD when the PS4 launches. Most certainly second hand ones. It's not as if they will suddenly cut all support from the PS3 (or for the matter for 360 too).
Sony is rolling out Gaikai to solve BC problems. As others have said, it's not a good idea to roll out 2 solutions for a relatively minor issue that probably only a few people will rip their hair out for.
Besides, Gaikai is, effectively, a multi-generation BC solution. One can totally imagine that if and when there is a PS5 that PS4 titles will most certainly be provided though Gaikai.
It is plausible that in 3 years time BC issues are completely obsolete due to this service working.
Making demands and complaining about stuff only gets constructive when they're actually rooted in reality.
Any executive pushing to design another complete SKU to work with PS/PS2/PS3 titles, testing it, and marketing it for a relative minority WHILE rolling out Gaikai service would probably be thrown out of the room within minutes.
So who do you tink pays for the servers for BC in the end, even if you never use them?
Who do you think pays for your cloud services?
The costs may not be upfront but they'll get to you somehow, even though it may not require you to do anything. The information you generate by "being alive" pays for cloud services to a certain degree.
Why not give the option to those who want it at a price and make it cheaper for the rest instead of forcing everyone to pay for youtube and serverfarms.
Probably because
1. It's cheaper for them to do this way in the long run.
2. It's cheaper for you to do it this way in the long run.
